ABSTRACT

In order to investigate the effect of organic and chemical fertilizers on quantitative and qualitative traits of Ducrosia anethifolia, a randomized complete block design was carried out with three replications. The experiment was performed with seven treatments including control (no fertilizer), manure (bovine), chemical fertilizers including nitrogen(N), phosphorus (P) and potassium (K), vermicompost fertilizer, thiobacillus bacterium, mycorrhiza fungi, and a combination of mycorrhizal fungi and thiobacillus bacterium (mycorrhiza+thiobacillus). Results showed that fertilizer treatments increased the yield and yield components of the plant compared to the control. Inoculation with thiobacillus, mycorrhiza, and thiobacillus+mycorrhiza resulted in higher levels of seed yield, essential oil yield and percentage, chlorophyll a, b and total and also carotenoids content compared to plants treated with chemical fertilizers. Generally, thiobacillus+mycorrhiza treatment led to more seed yield (8430 kg/ha) and essential oil yield (176.36 kg/ha) than other treatments, showing 62% and 52% increase in seed yield and 80% and 321% increase in essential oil yield in comparison with control and chemical fertilizers, respectively. Based on the results of this research, application of biological fertilizers can control excessive use of chemical fertilizers in sustainable agriculture.

摘要

为探讨有机肥和化肥对紫花苜蓿数量性状和质量性状的影响，进行了三个重复的随机完整区组设计。试验采用对照（不施肥）、粪肥（牛）、氮（N）、磷（P）、钾（K）等化肥、蚯蚓粪、硫杆菌、菌根真菌、复合肥等7个处理进行。菌根真菌和硫杆菌属细菌（菌根+硫杆菌）。结果表明，与对照相比，肥料处理提高了植物的产量和产量构成。与用化肥处理的植物相比，接种硫杆菌、菌根和硫杆菌+菌根导致更高水平的种子产量、精油产量和百分比、叶绿素 a、b 和总含量以及类胡萝卜素含量。一般来说，硫杆菌+菌根处理比其他处理导致更多的种子产量（8430 kg/ha）和精油产量（176.36 kg/ha），种子产量增加62%和52%，精油产量增加80%和321%分别与对照和化肥比较。基于这项研究的结果，生物肥料的施用可以控制可持续农业中化肥的过度使用。
